crawler: interleave tiers before cutting the batch; non-hot tiers starved - #283

…rved dueFeeds returns the pool tier by tier (quota x OVERREAD each) and spreadHosts took the first batchSize rows, so the hot tier alone filled every 900-row batch and active/slow/dormant/archived were never read while 383k rows were due. A subreddit queued at the front of the active tier sat at 1,081 of 2,700 and was never crawled. interleaveTiers orders rows by fractional position within their own tier, so any prefix keeps the 40/30/18/10/2 split and first-in-tier rows stay first.

Found while chasing why r/rss never got crawled: the tier quotas in dueFeeds were cut away by spreadHosts taking the first 900 of a tier-ordered 2,700 pool, so only the hot tier was ever crawled. Verified read-only against prod: before, r/rss not in batch; after, in batch.
